In Intacct:

Enable SSO for your Intacct company using the Company Information screen.

Go to the Company Information screen (Company > Company Info) and select the Security tab. Scroll down to the Single Sign On (SSO) section of the Security tab and enter the information provided by your SSO identity provider. This establishes a connection between Intacct and your SSO identity provider.

In the SSO Certificate field, paste your X.509 security certificate.Tip: If your certificate has an expiration date, remember to return to Intacct to update the security certificate.

Set up any Intacct users who will be logging in using SSO.

You can set up individual Intacct users for SSO by editing their user record (Company > Users > Edit). In the Federated SSO user id field, enter the ID that your identity provider uses to uniquely identify that user.

Any users who aren’t set up for SSO can continue to log into Intacct using the basic login screen. However, once a user has been set up for SSO, they will be required to use the SSO login.
